Asked the guy about HV app (550 volt range etc).
Any thoughts on this for a beginner scope?

REALLY appreciate any input :D

10 Mhz ...I'd likely go for a 30Mhz (20Mhz bare min)..the hi voltage
can be done with a 100:1 hi voltage probe for whatever scope you
buy...

Yeah.. sometimes I think too much for a guy who doesnt know anything!
If I have a circuit that is oscillating ultrasonic how will I know if
my scope is only 10mhz??

Don't worry, you'll be able to *slow it down* and read
ultrasonic frequencies... ultrasound is specifically defined
as frequencies above 20KHz... typical parasitic oscillations
in tube-type audio amps are normally well below the megahertz
range... and even if you can't resolve the sine wave, you'll
see the creamy-white wide trace and identify it as stuff you don't
want.  Ten is more than enough.

Thanks!!  I will read the voltage divider stuff in the morning after
my second coffee :D- Hide quoted text -

Picked up the scope for 140$ (silly clean.. bright traces).
No probes or manual but I can live with that for now (until I learn
how to use it will use the homemade probes on low voltage stuff)
Thanks for all the advice.

Cheers

Drew

Forgot..there's a scope group on Yahoo that will give advice also...- Hide quoted text -

Cool.. thing that gets me bout the bay is the shipping from US.
8$ item and 23$ shipping (and I have been nailed for duty before too).
What is the diff between the cheapy probes and quality brand ones?
